Integers in Python can be as big as the bytes in your machine's memory. There is no limit in size as there is: (c++ int) or (C++ long long int).

As we know, the result of grows really fast with increasing .

Let's do some calculations on very large integers.

**Task**

Read four numbers, , , , and , and print the result of .

**Input Format**

Integers , , , and are given on four separate lines, respectively.

**Constraints**

**Output Format**

Print the result of on one line.

**Sample Input**

```
9
29
7
27
```

**Sample Output**

```
4710194409608608369201743232
```

**Note**: This result is bigger than . Hence, it won't fit in the long long int of C++ or a 64-bit integer.
